Warning: is using native unit of measurement 'A' which is not a valid unit for the device class ('energy')

I get the following warning message in Homeassistant for the fields i1, i2 and i3:

I guess this entities needs state_class: measurement and device_class: current instead of total_increase and energy.

Can you try the -dev addon? #20

[matze338]

Thanks i1, i2 and i3 now works, but

in the dev-Version i get some "weird" decimal numbers

is this behavior correct?

[kellerza]

I'm not sure if anything changes wrt rounding (vaguely recall someone wanting 3 decimal points)

But in the latest HASS frontend you can change how many you want displayed, on a per sensor basis
